Snyder.

LANSING — Governor Snyder has urged federal officials to reconsider their denial for funds to help deal with the crisis caused by lead-contaminated water in the city of Flint, his office said on Thursday.

The contamination and the state’s long delay in addressing the problem have sparked outrage and drawn attention from presidential candidates.

In the latest appeal to the Federal Emergency Management Agency, Snyder is requesting money to pay for food, water and other essential needs; the removal of health and safety hazards; activation of emergency operations centers; measures to avoid further damage and homeowners’ repairs not covered by insurance.

A FEMA spokesman said Snyder’s appeal was under review by the agency.

The agency turned down an earlier request for financial help in January because the areas in which Snyder requested aid were deemed not appropriate, but has provided non-monetary support in the form of a FEMA coordinator.

Also in January, Snyder asked for federal declarations of emergency and major disaster. President Obama approved the federal emergency declaration, but denied a major disaster declaration. Snyder appealed that decision and was denied.

Snyder said on Thursday that Flint needed continued local, state, federal and national efforts. “Assistance from our federal partners could go a long way in moving Flint forward,” he said.

Activists and some Democratic state lawmakers have demanded that Snyder resign, but a spokesman said the Republican governor had no intention of stepping down.

Snyder is scheduled to testify before a Congressional committee on March 17.

Also on Thursday, Snyder said the federal government approved a waiver allowing for Medicaid coverage for children and pregnant women in Flint as part of the recovery efforts.
